Excellent finance (7)
I believe the answer is:
capital
This clue is a double definition.
'excellent' is the first definition.
(I've seen this in another clue)
'finance' is the second definition.
(thesaurus)
(Other definitions for capital that I've seen before include "Block" , "Major city - investment - excellent" , "Topping" , "A country's main city" , "Money saved or invested - seat of government" .)
